Blower Motor: Description and Operation
Manual A/C
Voltage is applied at all times through fuse 56 to the blower motor relay contacts. With the ignition switch ON (II), the blower motor relay is energized
which feeds battery voltage to the blower motor.
The heater fan switch then applies ground to the blower motor resistor for the desired blower motor speed. Each time you turn the heater fan switch to a
higher speed, more segments of the blower motor resistor are bypassed. This increases the blower motor speed. When the heater fan switch is in position
4, the entire resistor is bypassed and the blower motor runs at the highest speed.
